My last biome is Tundra

My last biome i would like to talk about is tundra. The tundra biome is at the top of the world mostly near the north pole. I have traveled to enviorment that is tundra which is Alaska. In enviorments like Alaska has extremly cold climates and low biotic diversity-Not to menchine that tundra is the coldest biome. Tundra enviorments has simple vegetation structure & energy and nutrients in the form of dead organic material. Tundra is in the high moutains all around the world.
